2.錯綜時間條件句
if虛擬條件句主句與現(xiàn)在事實(shí)相反的假設(shè)與過去事實(shí)相反的假設(shè)與將來事實(shí)相反的假設(shè)1、If+主語+動詞過去式2、If+主語+wereto+動詞原形3、If+主語+should+動詞原形If+主語+動詞的過去式(be動詞一般用were)主語+would(should/might/could)+動詞原形即:If+一般過去時態(tài)(be動詞一般用were)If+主語+had+動詞的過去分詞即:If+過去完成時態(tài)主語+would(should/might/could)+havedone主語+would(should/might/could)+動詞原形錯綜時間條件句錯綜時間條件句2.
錯綜時間虛擬條件句即:if虛擬條件句與主句的時間不一致。1).Ifyouhadfollowedmyadvice,youwouldbeabletofinishtheworknow.如果你當(dāng)時聽了我的話,現(xiàn)在就能完成這份工作了。(從句說明過去,主句說明現(xiàn)在。)2).IfIwereyou,Iwouldhavegonetoherbirthdayparty.如果我是你,我就去參加她的生日晚會了。(從句說明現(xiàn)在,主句說明過去。)3).Ifyouhadn’tlentmesomemoney,Icouldn’thaveboughtthenewhouseandmostlikelyIwouldbestilllivinginthedangeroushousenow.假若你不借錢給我,我不可能買下這幢新房,很可能現(xiàn)在還住在危房里。(從句說明過去,主句說明過去和現(xiàn)在。)1.IfI_________(be)you,Iwouldhavetakenhisadvice.2.Ifit__________(snow)lastnight,itwouldbeverycoldtoday.3.IfI_________(work)hard,Iwouldbelivingahappylifenow.4.Hadyou_________(study)harderlastterm,youcouldhavepassedtheexam.
werehadsnowedhadworkedstudied3.省略if的用法:在虛擬條件句中,如果條件句中有were,had(助動詞)或should時,可使用倒裝結(jié)構(gòu),但if必須省略。
1).HadIseenhimthen,Iwouldhavebeenveryhappy.=IfIhadseenhimthen,Iwouldhavebeenveryhappy.2).ShouldIhavetime,Iwouldgowithyou.=IfIshouldhavetime,Iwouldgowithyou.3).WereInotsobusy,Iwouldgowithyou.=IfIwerenotsobusy,Iwouldgowithyou.(5)含蓄條件句,有時為了表達(dá)的需要,在虛擬語氣中并不總是出現(xiàn)if引導(dǎo)的條件句,用介詞短語代替條件狀語從句.常用的介詞有with,without,butfor等。如:1.Whatwouldyoudowithamilliondollars?2.Wecouldnothavefinishedtheworkaheadoftimewithoutyourhelp.3.Butfortherain,wewouldhavefinishedthework.=Ifyouhadamilliondollars,whatwouldyoudo?=Ifwehadn’tgotyourhelp/Ifyouhadn’thelpedus,…=Ifithadn’tbeenfortherain,…(4)Iwasillthatday.Otherwise,Iwouldhavetakenpartinthesportsmeet.(副詞)(5)Hetelephonedtotellmeofyourbirthday,or/otherwiseIwouldhaveknownnothingaboutit.(連詞)陳述語氣虛擬語氣陳述語氣虛擬語氣5.“建議/命令/要求”虛擬(1)V+賓語從句(should)+do建議:suggest,propose,advise命令:order,commend要求:ask,request,require,demand,desire(希求),prefer,主張:insist(堅持要求),maintain,hold,urgee.g.Isuggestthatshe(should)stayathome.
(2)N+同位語從句(should)+doN+is+表語從句(should)+dosuggestion/requirement/desire/necessity/recommendation/wish/decision/proposal/demand/….e.g.Weallagreedtohissuggestionthatwe(should)gotoBeijingforsighting.=thesuggestionisthatwe(should)gotoBeijing…=Isuggestthatwe(should)gotoBeijing.=ItissuggestedthatweshouldgotoBeijing.(3)Itis+adj.+主語從句(should)+doIt+is+suggested/desired/required+that…(should)+doe.g.Itissuggestedthatyou(should)finishthefirststep.
7.固定句式.Itis(high/about)time
(that)“是時候…...(做某事)”
注意:should不能省略.sbdidsbshoulddo是時候采取措施來保護(hù)環(huán)境了。Itis(high/about)timethatwetook/shouldtakemeasurestoprotecttheenvironment.你該走了。It’s(high/about)timethatyouwent/shouldgo.2.wouldratherthat現(xiàn)在:過去:未來:過去時過去完成時過去時(1)Iwouldratheryou
